Damage Condition
Wear occurs due to repeated sliding between the
two surfaces. Fretting occurs at fitting surface and
also at contact area between raceway ring and
rolling elements. Fretting corrosion is another term

Possible Cause
Poor lubrication
Vibration with a small amplitude
Insufficient interference
Countermeasure
Use a proper lubricant
Apply a preload
Check the interference fit
Apply a film of lubricant to the fitting surface
